Scanners and scanner housings

1. A scanner, comprising: a housing to carry an optical element, the housing having a first support feature; and a printed circuit board having a second support feature to mate with the first support feature of the housing, the first and second support features to reduce a vertical load on the housing by transferring a portion of the vertical load to the printed circuit board when the first and second support features are mated.

2. A scanner as defined in claim 1 , wherein the printed circuit board comprises an optical component for an image scanner.

3. A scanner as defined in claim 1 , wherein a first one of the first support feature or the second support feature comprises a tab and the other of the first support feature or the second support feature comprises a slot to receive the tab.

4. A scanner as defined in claim 1 , wherein the first support feature is one of at least three tabs, and the second support feature is one of at least three slots, the at least three slots to mate with the at least three tabs.

5. A scanner as defined in claim 4 , wherein the tabs and the slots are to mate to transfer the portion of the vertical load from the housing to the printed circuit board.

6. A scanner as defined in claim 1 , wherein the housing and the printed circuit board have a vertical height less than about 6 millimeters.

7. A scanner as defined in claim 1 , wherein the first support feature comprises a first slot and the second support feature comprises a second slot, the first and second support features to be joined by a fastener.

8. A scanner as defined in claim 1 , wherein the first support feature and the second support feature are to remain mated in response to thermal expansion or thermal contraction of the housing or the printed circuit board.

9. A scanner as defined in claim 1 , wherein the housing comprises at least one of thermoplastic or thermoset plastic.

10. A scanner as defined in claim 1 , wherein the first support feature is dimensioned to permit the second support feature to move laterally while substantially maintaining a flatness of the housing.

11. A scanner, comprising: a housing to carry an optical element; and a printed circuit board having a first intrinsic stiffness in a first direction and a second intrinsic stiffness in a second direction perpendicular to the first direction, the second intrinsic stiffness being less than the first intrinsic stiffness, the printed circuit board to mate with the housing such that the printed circuit board provides support to the housing in the first direction.

12. A scanner as defined in claim 11 , wherein the printed circuit board comprises an optical component for an image scanner.

13. A scanner as defined in claim 11 , wherein the housing and the printed circuit board are to mate to transfer at least a portion of a load in the first direction from the housing to the printed circuit board.

14. A scanner as defined in claim 11 , wherein the housing and the printed circuit board have a vertical height less than about 6 millimeters.

15. A scanner as defined in claim 11 , wherein the housing and the printed circuit board are to remain mated in response to thermal expansion or thermal contraction of the housing or the printed circuit board.

16. A scanner as defined in claim 11 , wherein the housing comprises at least one of thermoplastic or thermoset plastic.

17. A scanner as defined in claim 11 , wherein the housing and the printed circuit board are mated such that printed circuit board is permitted to move laterally while substantially maintaining a flatness of the housing.

18. A scanner as defined in claim 11 , wherein the first direction is more vertical than horizontal.

19. A scanner, comprising: a housing to carry an optical element, the housing comprising three first support features; and a printed circuit board comprising three second support features to respectively mate with the first support features of the housing, the first and second support features to reduce a vertical load on the housing by transferring a portion of the vertical load to the printed circuit board when the first and second support features are mated.

20. A scanner as defined in claim 19 , wherein the three first support features are three tabs, and the three second support features are slots, the slots to mate with the tabs.
